Rapid Degradation of Phenanthrene by Using Sphingomonas sp. GY2B Immobilized in Calcium Alginate Gel Beads
The strain Sphingomonas sp. GY2B is a high efficient phenanthrene-degrading strain isolated from crude oil contaminated soils that displays a broad-spectrum degradation ability towards PAHs and related aromatic compounds. This paper reports embedding immobilization of strain GY2B in calcium alginate gel beads and the rapid degradation of phenanthrene by the embedded strains. Results showed that...
متن کاملConjugal transfer of plasmid DNA between streptococci immobilized in calcium alginate gel beads.
A rapid and simple technique was developed for conjugation between group N and group D streptococci by using cells entrapped within calcium alginate gel beads. With this method, the frequencies of transfer of lactose metabolism from Streptococcus lactis ME2 to S. lactis LM2302 were comparable to those achieved with agar surface matings. Conjugal transfer of the chloramphenicol and erythromycin ...
متن کاملEnantiomerically Pure D-Phenylglycine Production using Immobilized Pseudomonas aeruginosa 10145 in Calcium Alginate Beads
Em trabalhos anteriores em nosso laboratório, uma cepa de Pseudomonas aeruginosa demonstrou ter atividade enzimática na conversão de arilaminonitrilas em D-amino ácidos. Essa atividade enzimática aumentou por indução de modo a produzir D-fenilglicina enantiomericamente pura a partir de 2-fenil-2-aminoacetonitrila. No presente trabalho, as melhores condições para essa transformação são descritas...
متن کاملBiodegradation of crude oil by immobilized microbial cells in alginate beads produced by electrospraying technique
Background and Objective: Petroleum compounds are major contributors to aquatic environmental pollution. In recent years, biological treatments as environmental-friendly and cost-effective techniques have been used alongside the various physico-chemical methods. Microbial cell immobilization in hydrogel carriers has been the focus of researchers due to various advantages such as ease of microbi...
متن کاملSHOOT REGENERATION FROM SAFFRON PROTOPLASTS IMMOBILIZED IN Ca-ALGINATE BEADS
Saffron (Crocus sativus L.) protoplasts were isolated from the cells of a suspension culture or calli with a solution of Cellulase, Pectinase and Hemicellulase and embedded in Ca-alginate beads. They were cultured with or without nurse cells in MS medium supplemented with 2,4-D and 6-benzylaminopurine at 25°C. After several changes of medium, cell-clusters appeared on the surface of the Ca-algi...
